LAMP OR LANTERN.

SPECIFICATION forming part of Letters Patent No. 374,144, dated November 29, 1887.

Application filed February 10, 1886. Serial No. 191,438. (No model.)

To all whom it may concern: Eisthefglobawhich is supported upon cham- Beit known that I, CHARLES G. DYOTT, of ber A and located between it and the adjustthe city and county of Philadelphia, and State able section I of the chamber B, which adjusto,f Pennsylvania, have invented an Improveable section is provided with a cap, G, having v 5 ment in Lamps and Lanterns, of'which the thedownwardly-projecting tubularshieldg, to following is a specification. hide the upper or ragged portion ofthe iiame.

is essentially an improvement upon what is Kis the Argand burner, which consists of an shown in said Letters Patent, and has particuannular chamber with a number of vertical lar reference to that class of lamps. Many tubes or burners, and is located between the parts of the invention are equally adapted to deflector F of the case or chamber A and the 75 25 other forms of lamp, such as those of Sievapor-chamber L. The top ofthe vapor-chammens, Hoofman, Lipsey, Schulke, Sanderson, ber L is provided with the vaporizer M, andv &c., and therefore I do not in any wise limit consists of a solid metallichead having lateral myself to any particular forni. passages N and an oil-aperture, m, adapted Myixnprovements consist, chieiiy, in a more to be closed or opened by the needle-valve R, 8o

tion ofahydrocarbonlainporlantern embody- Extending upwardly above the vaporizer ing my improvements. and carried thereon is the heat-conductor O, go

4o A is the lower chamber, and B is the upper which may be made like a tube or any other chamber, the two being connected by the reshape desired. This conductor extends up 'turn-dues C, whose function is to return the into the tubular shield g, and is heated by the y hot products of combustion, or that part caught escaping products of combustion,l and in turn by the vessel D, located in the chamber B and conducts its heat down to the vaporizer M, 95

4 5 provided with the contracted or funnel-shaped and even to the tube Q. It also heats the va- ,orice d, to increase the draft upon the por-chamber L, and thereby keeps the vapor ascending products and force them down the from condensing when once it is formed. The tubes G, from which they emerge into the botvaporized oil passes into the vapor-chamber tom of the chamber A,preferably between the at the top and descends to the burner. It is roo 5o screens T T, and are mixed with the ascending preferably caused to pass through one or more fresh air. screens, Z, to thoroughly mix and equalize its distribution, whereby all flickering or j umping at the burner is obviated.

Pis a detlector of refractory material, which is used to deect the dame, throwing it somewhat outward, and, being made of a light or white material, it acts as a reflector, increasing the brilliancy of the ilame and the candlepower of the lamp. This deilector P is made cylindrical or cup-shaped, and extends around the vaporizer and vapor-chamber, and is supported upon the latter. It preferably does not `touch the vaporizer or upper part of the vapor-chamber, but forms an annular deadair space around them, preventing changes in their-temperature, which would take place if not thus surrounded and protected from draft. There being more air-space between the burner K and dellector F than between it and the vapor-chamber L, I provide the annular' disk or screen U, arranged upon the outside only of the burner, as shown, leaving an open annular space, u, for free passage of air; or, if desired, the screen U may be open-meshed and extend to the case or chamber A. This will insure as much air passing upon the inside of the burner-tubes as upon the outside of them, and will cause a uniform flame and one in which the carbonaceous products are fully consumed.

Vtis an auxiliary1 valve-body which receives oil` from the vertical oil-tube Q.

X is a valve working in the valve-body WV, which extends outside of the case or chamber A, and is used to supply oil to the lighting-cup S, located below the oil-outlet s from the valvebody and surrounding the oil-tube Q, and to Ywhich said tube isY attached. This lightingcup is supported by a frame riveted to the chamber A, and through its mediation the vaporizer, conductor, vapor chamber, and burner are sustained in position within the lamp.

Y is a covered passage-way or door placed in the casing A, and in such a position that the lighting-cup may be reached through it with a lighted match to taper. when starting the lamp. The valve R being closed and valve X being opened, oil will pass from pipeVinto vertical pipe Q and out through passage s into the lightingcup S. The valve X is then shut oft` and the oil inthe cup ignited. The ame of the burning oil surrounds the vertical oil-pipe Q and envelops the Argand burner, and the vapor-chamber and these parts by conduction heat the vaporizer. Oil is then admitted to the vaporizer by opening the valve R slightly, and the vapor passes through the chamber L to the burner K. During these operations air is supplied as the supporter of combustion in the manner hereinbefore specified-that is to say, up through the screens T in the lower chamber, A, and up to the burner. This air would be heated if the products of combustion were returned by pipes C. The burner-flame now passes upward around the deilector P and into the shield g, heating the conductor O, which in turn heats the vaporizcr and keeps it hot and insures its action without aid from the lighting-cup. The escaping products of combustion pass up through case B and directly into the atmosphere, or may be conveyed away by pipes, and that portion ofthe products collected by the vessel D passes back down the pipes C to the chamber or case A, and mixes with ascending air, imparting heat to it to furnish the lamp with a hot-air supply, as hereinbefore set out.

I do not limit myself to the particular details of construction shown, as it is evident that the parts may be modified in various ways without departing from my invention. For instance, the conductor O might be solid or given other shapes, and in place of the de- `flector P two disks, as indicated in dotted lines, might be used.

I am well aware that in heating-stoves using oil vapors it has been proposed to supply oil to the lighting-cup by a separate valve from that supplying oil to the burner; but beyond this similarity and the location of the lightingcup under the generator there is practically no similarity with my invention. Such stoves are set out in Patents No. 270,587, Vof 1883, and No. 255,245, of 1882.-

In 1885 a patent, No. 326,550, was granted to me for a gas-burning lamp, said patent also showing the application of oil as the illuminating agent, and this application is for an im provenient upon said Letters Patent.

Having now described inyiuvention, whatI claim as new, and desire to secure by Letters Patent, is-

l.
